SP Engine diameters for stage planning

Playing RP-1 and finding yourself frustrated with tooling because you don't know what is coming later and feel like you can't make informed planning?

While documenting ALL the engines in RO would be a large task, the purpose of this document is to document all the Procedural Engines provided by the SPE mod to aid in planning.

Minimum Tank Diameter Definition: As this could end up being a subjective measurement based on looks, I decided to use very specific criteria to keep it objective. The tank diameter listed below is the minimum tank diameter necessary when using ROTanks such that a shroud would cover the top section of the engine (not the bell) without any dangly bits sticking through (Yes dangly bits is a technical term).

Also note I used on preset increments and did not use any values between two presets.
